Error: ENOTDIR, not a directory

[dr-nyt]

Hello,
I'm creating a desktop app that is built on Electron with AngularJS. Before building as a production app, this module works as intended, amazing work. But after packaging it into a release build, it gives the following error: Error: ENOTDIR, not a directory.

This is probably some incompatibility with angular or something and I'd like some help fixing this bug.
The download path provided is:

let option = {
      title: novel.info.name,
      author: novel.info.author,
      cover: novel.info.cover, 
      content: chapters
};
new epubGen(option, "A:\Downloads\My new book.epub");

The issue seems to originate at EPub.generateTempFile (C:\resources\app.asar\node_modules\epub-gen\lib\index.js:234):

generateTempFile() {
      var base, generateDefer, htmlTocPath, ncxTocPath, opfPath, self;
      generateDefer = new Q.defer();
      self = this;
      if (!fs.existsSync(this.options.tempDir)) {
        fs.mkdirSync(this.options.tempDir);
      }
      fs.mkdirSync(this.uuid);        <=========================== ERROR HERE
      fs.mkdirSync(path.resolve(this.uuid, "./OEBPS"));
      ...

I was wondering what uuid is for and if it could lead to fixing the bug.
Kind Regards,
dr-nyt.

I should probably also make it clear that I have made files and directories in that path directory using the fs module.

As much as I like this module, the only solution I came across was to use another module called nodepub. This module and Electron/Angular don't go well together for some reason and hopefully, a fix is found soon.

I will keep this issue open unless the dev decides to close it or a fix is found.
